Alright so I'm having trouble controlling my humidity. When the lights on, the humidity isn't terrible average 65%. It's when the lights go off and the temps aren't going up as quickly. I have my exhaust fan plugged into a controller that turns the fan on when it is 77 and when it gets below that it turns off. I just went and bought a speed controller for the fan to see if that will help keeping my humidity low during the night. I just went and bought a 14k btu dual hose ac which does a goodjob. The air conditioner also says that it is a dehumidifier [ame=http://www.amazon.com/Haier-CPN14XC9-14K-Portable-Conditioner/dp/B003GTB1M8]Amazon.com: Haier CPN14XC9 14K Portable Air Conditioner: Home & Garden[/ame] but I haven't been too impressed with that function. I don't really want put a dehumidifier in the room since I already have a bulky ac/dehumidifier in there and I also don't want the extra heat.
